To all whom it may concern:

Be it known that I, ALBERT C. MURPHY, a citize'nof the United States,and resident of New York, count of New York, and

State of New York, ave invented an Imrovement' in Dumping-Cars, of whichthe ollowin --is a specification.

The 0 ject of m invention is to provide a construction of umpingcar forrailway purposes, which'may be used either for construction work or forcarrying ore or other material in bulk, the car being so constructedthat the contents thereof may be dumped to either side of the track in aspeedy and satisfactory manner. My object is further, to providesuchdumping car with aplurality of separate dumpmgcompartments or bodies,which.may be separately oscil: lated from the? ends of the car, wherebyfractional portions of the 'total'load may be dumped atdifl'erent'places on the sameor different sides of the-track, whenrequired.

In carryingmy invention into' practice, I provide a main car framesupported at each end upon truckst thecndso thecar frame havingplatforms (l1oused if desired) and containin the operative means forcontrollingthei um ing,.said frame provided with one or more ox bodiessupported upon the car framein such mannerasfto be capable of rocking.more or less similar-to a cradle, and ada )ted todumpto. either side ofthe car, sai box bodies being actuated by the operative: means forcontaolli'ng' the doinging,-- whereby the-said action-may be detrolledfrom-"theiend or-ends' of the car.

y' invention-further" consists in so conrespect to the. longitudinalline of the car frame :du ringtl'ie act of dumping, so as to cause thesaid'ceuter of ravity to remain substantially over't'he' amsof rockingcontact ofthe car bodies with the" car rame, whereby the manipulationof-the said bodies .may be more easily acwmplisbedand no un he strainputupon the dumping mechanism. My object is further, to provide meansfor*locl '1n5 tliebox bodies in their normal horizont position upon thecar frame, soi that in transport the said bodies will not blpermitted tooscillate Myiuvention-wlso comprehends many details of constructionwhich, together with the features above specified,- Will be betterunderstood by reference to the drawings, in which Figure 1 is a sideelevation of a; dumping car embodyin my invention; Fig. 2 is a plan viewof t e same with the cabs in section; Fig. 3 is a cross section of thecar showing one of the box bodies rocked to dumping position; Figs. 4and 5 are sections showin details of the rocker bed; Fig. 6 is a sideelevation with part in section,-showing the means for operatin thetilting means; and Figs? and 8 are e evations of portions of the same.

2 is the main or car frame and ma consist of a longitudinal girderconstruct on of anysuitable form capable of providing the stren requiredfor a car of this type. As own, it com rises the longitudinal 'rde'rs2"connet across at the top and avin transverse bottom angle plates 2exten ing laterally of the girders in the brackets 2 under the bodies ofthe car. The car frame is ivoted near each end upon the trucks 3 whichmay, if desired, be electrically or otherwise driven, as is well knownin railway practice This car frame 2 is also preferably provided at itsends with platforms 4, which may be housed by suitable cabs 5 forcontaining the devices for performing and controlling the dam ing andfor protecting the workmen. If the car is electrically propelled, thesecabs may also act as protectlon to the motorman as 1n the case 0 mosttrolley cars. \Vhen my im roved car is used as a trailer in a train, (I,'ecabs at the ends may be dispensed with and the platforms reduced to aminimum area to provide a working support for theoperator who controlsthe dumpmg.

Intermediate of the end platforms are arranged a lura-litv of dumpingbox bodies 6, said bo( ies each supported upon rockers 7, rocking upontransverse beds 8 built into and transversely of the ear frame 2 andextending to each side of the central lon 'tudinal line of the car. Thebottoms of t ese box b xlie's have longitudinal beams 9, 9" and 9,between the beams 9- of which, near each end of the bodies, are thetransverse rockers 7. The beams 9 are preferably of shape as to lock therockers in These rockers fit around t Patented May 29, 1917.

)lace (Fig. 3) V e longitudinal '1 beam 9" and extend between thelmamsf9'11o:

and are rigidly secured in place. They are provided with teeth 10 whichengage teeth 12 upon the transverse beds 8. This construction preventsthe sliding displacement of the body during the act of dumping or duringrough usage of the car in act of transportation. The beds 8 have sides8* at each side of the teeth 12 which prevent displacement of therockers 7 in the direction of the length of the car. Moreover, to causethe body to maintain a normal horizontal posit-ion upon the beds of thecar frame, 1 form the. bed 8 and rocker '7 at their middle portions withextended flat-- tened portions 13 and 14: respectively, which, when indirect contact, cause the body to assume and maintain a. horizontalcondition, when it is brought to approximately a central normalposition. The spaces between the teeth of the rocker beds 8 arepreferably open as at 16, to permit any dirt to pass freely through andnot obstruct the action of the rocker (Figs. 4 and 5.)

The box bodies are open attheir sides, except so far as the doors 17close them, said doors being hinged at 18 to the under side beams 9 andarranged to close against the upper side angle irons 20 of the body.\Vhen closed, the doors may be locked by the hooks or latches 19. Theparticular construction of the doors and their manner of hinging,locking and releasing, may be varied. In the two end box bodies, haveshown division plates (5, by which the bodies are divided intocompartments open at each side of the car except for the doors 17. Byuse of these division plates, the bodies are stiffened trai'isverselyand provide capacity for carrying separate classes of materials at onetime, or different portions'of the same material. These division plates6 may be omitted, if desired.

To rock the box bodies, the following mechanism is provided: The carframe 2visprovided with a plurality of shafts-24, 25, 26 and 27respectively leading to a. position under each of the box bodies (5.(Fig. 2), and said shafts extend to the ends ofthe car. As shown, twoof these shafts, 24 and25, extend to one end of the car, and the othertwo shafts, 26 and 27, extend to the op osite' end of the car. Theshafts are journaiied in the brackets 2 and also in bearings 30 adjacentto the ends of the car frame. Adjacent the brackets 2 and below the boxbodies each of the shafts is provided witha pinion 28 adapted to meshwith an adjacent rack 22. It will be understood that there is a rack 22for each pinion, and the said racks are respect'ivelyjgnided in contactwith the pinion by the respective uide rollers 29 which are alsojournaled in t e-respective brackets 2. yfhe upper end' of the rack 22is hinged to the under side of thebox body, or more specifically to thebrace plates 9" securedthereto (Fig. 3). The lower portion of the rackis provided with a shoulder 23, which may contact with the guide roller29 when the rack is fully elevated, to prevent disengagementa Byrotating the shaft and its pinion '28 in one direction or the other, thebox body 6 may be tilted or rocked to either side of the carframe; andthe braces 9 may act as abutment stops to limit the tiltin movement bycoming 1n contact with the brackets 2 (Fig. 3). Furthermore, when thebody is rocked 'or tilted to its full extent, the shoulder 15 of therocker 7 abuts against the end of the rocker bed 8 and this enables thebody to be 'held against shifting laterally under horizontal thrusttoward the center of the car by the slidin of the con tents of the bodydown the inc ined floor or bottom.

The other ends of the several shafts, beyond the bearings 30, areprovided with sprocket wheels 31, and theseare rotated by operativemeans in the cabs 5, at each end of the car. Thevconstruction of theseseveral means is best shown in Figs. 6, 7 and 8, and comprises asuitable frame '46 in which is journal-led a sprocket 'pinion 33 havinga gear 34. A chain 32 connects the sprocket pinion 33 with the'sprocket'wheel 31. The gear 34 meshes with a pinion 35 36 and'alsohaving a. detent wheel '38. By rotating the hand wheel 36, the sprocketsecured to a shaft 37 having a hand wheel wheel 31 and its shaft vmay berotated in either direction. A double acting pawl 39 pivoted on a pin 40engages the detent wheel 36. This pawlmay be; oscillated and s )ringpressed into engagement with the etent wheel by the spring, which hasone end connected with thepawl 'and'the other end with the arm 42. Thisarm 42 is hinged at 43 to the frame 46 above the pawl (Fig; 8), and maybe thrown about its hinge point to either side of the detent wheel 38,in which case the mit the s tion onl the-box ii aft 37' to be rotated ineither 'dinecat onetime and gnay act'to hold ody in its tilted or rockedposition.

When the body is in a horizontal position durlng transportation, it isdesirable to lock the rack 22 when in the position shown-at left hand ofFig. 3; this may be accomplished by throwing the arin42 to a 'verticalposition and inserting the pin 45 to hold it there. This action causesthe notched end 44 to towar the detentwheel 38 so. that both pawl willbe required to act'to per-.

press upon the pawl 39 and force it pawl teeth come into'enga'gementwith the detent wheel at the same time, as indicated in dottedlines, andthus lock the shaft 37 against rotation in either direction. Any

other suitable locking means may be employed in place of that here shownby way of example. The operative means is such, that one manmay rock aloaded body with lieu of that shown and may be operated by mechanicalpower, such as electricit if it is available, though ordinaril manuapower is found amply sufficient. s shown, there are two of theseoperative means for each cab and for ,two shafts, thereby providing forthe four shafts, four of these operative means distributed in pairs atthe two ends of the car. The general construction of car here shown isadapted for one or more bodies and hence I do not restrict myself to thenumber of such bodies.

To enable the bodies to be easily and quickly rocked by one man, it isadvisable to so proportion the construction of the body and its rockersupports that the approximate center of gravity G is substantiallvvertically above the axial line of contact of the rocker 7 with therocker beds 8, as indicated in Fig. 3. The ertical line from ,Gwillshift laterally as the body approaches a horizontal osition and whenthis is reached, the

. vertical line of thnist will be central of the car. The same resulttakes place on either side of the central line as the body is tilted toone or the other side of the'car. At all positions, the verticaldownward thrust from the center G of. gravit extends approximatelythrough the axia line of contact between the rockersand their beds.

I have shown. my improvements in the form which I have found mostsatisfactory in actual use; and while I prefer the construction shown, Ido not restrict myself to the details, as these may be modified withoutdeparting from the spirit of the invention. I In this application, Imake no claim to the specific construction of the box body havingtransverse divisions and a plurality of doorsat each side, as that willform subject matter .of a separate application.

Matters'shown inthis application and not claimed which relate to therocking box body and means for tilting and locking the same, formsubject matter of my application Ser. No. 848,728, filed June 3, 1914;and further I make no claim to the specific construction of the box bodyhaving transverse divisions and a plurality of doors at each side, asthat will form subject matter of a separate divisional application.
